Abstract: PURPOSE: A method for manufacturing an isolation layer of a semiconductor device is provided to guarantee a desired active region by preventing a bird's beak from being generated, and to improve an insulating characteristic by preventing a defect in forming an insulating layer. CONSTITUTION: After a silicon layer is formed on a silicon substrate(11), the silicon layer is oxidized to form an oxide layer. After a photoresist layer pattern is formed on the oxide layer, the oxide layer is etched to expose the silicon substrate by an etching process using the photoresist layer pattern as a mask. The photoresist layer pattern is removed to perform an annealing process. A silicon epi-growth layer(14) is formed on the exposed silicon substrate. A planarization process is performed to make the silicon epi-growth layer become an active region and to make the oxide layer become an isolation layer.
